Many thanks - but I am unable to configure Buildroot to give an EABI
compatible (version != 0) toolchain.
I have now tried also using the most recent GCC and Binutils in the
Buildroot menuconfig options, this using buildroot-20061031.

What is the required 'GNU target suffix' or other setting to enable
EABI operation ? (Obviously I have set 'Target ABI: EABI')

The only target suffix that appears to give a workable toolchain
(i.e. one that doesn't say 'unrecognised emulation mode') 
is 'elf-linux', and that doesn't seem to support EABI (objects built
with it have EABI version 0)

If I use any other target suffix settings in the menuconfig 
(e.g. elf-linux-eabi or even tried elf-linux_eabi) I get:
".../bin/ld: unrecognised emulation mode: armelf_linux
Supported emulations: armelf_linux_eabi" ... but I am unable to
obtain that setting :(

Regards,
Mike
